Despite the importance of polyploidy and the increasing availability of new genomic data,
there remain important gaps in our knowledge of polyploid population genetics. These gaps …

A compound hypothesis positing that self‐fertilization is an evolutionary dead end conflates
two distinct claims: the transition from outcrossing to selfing is unidirectional; and the …

The Brassicaceae include several major crop plants and numerous important model species
in comparative evolutionary research such as Arabidopsis, Brassica, Boechera …

Recent advances in the genomics of polyploid species answer some of the long-standing
questions about the role of polyploidy in crop species. Here, we summarize the current …

Colonization is likely to be more successful for species with an ability to self‐fertilize and
thus to establish new populations as single individuals. As a result, self‐compatibility should …

Plants have evolved diverse self-incompatibility (SI) systems for outcrossing. Since Darwin's
time, considerable progress has been made toward elucidating this unrivaled reproductive …

Selfing has evolved in animals, fungi, and plants, and since Darwin's pioneering study, it is
considered one of the most frequent evolutionary trends in flowering plants. Generally, the …

The prevalence of polyploidy in wild and crop species has stimulated debate over its
evolutionary advantages and disadvantages. Previous studies have focused on changes …

The self‐incompatible species Arabidopsis halleri is a close relative of the self‐compatible
model plant Arabidopsis thaliana. The broad European and Asian distribution and heavy …

Self-incompatibility (SI) systems in flowering plants distinguish self-and non-self pollen to
prevent inbreeding. While other SI systems rely on the self-recognition between specific …
